Andromeda is also known as Messier $31$ or $NGC\,224$. The Andromeda galaxy is believed to be more massive than the Milky Way galaxy. The count of stars present in this galaxy is as twice as that of the Milky Way galaxy. It is at a distance of $2.5\,million\,light\,years$ from the earth. It is the nearest major galaxy to the Milky Way galaxy that we live in.

Thus, the option (A) is correct.


Note:A study says that Andromeda and the Milky Way galaxy are expected to collide each other in around $4.5\,billion\,years$ and to become the same galaxy which is giant and larger in size. This Andromeda galaxy appears when excluding the clouds in the northern latitude. It appears as the dotted full moon.
